Brad Mills was hired before the 2010 season by Drayton McLane, who is no longer the Astros’ owner, and Ed Wade, who is no longer the Astros’ GM. So he’s been a sitting duck under the new regime.

And a 39-82 record sure didn’t help matters.

Mills was let go on Saturday night following an ugly eight-run loss to Arizona, along with hitting coach Mike Barnett and first base coach Bobby Meacham.

Interims for those positions will be named Sunday.

Mills, a first-time manager, went 171-274 in just shy of three seasons with the ‘Stros. His roster was sapped of talent over the past two summers as the organization began a frantic rebuild, but that brutal winning percentage means it will likely be a little while before he’s given another try as a major-league skipper.

The Astros are moving quickly to change the look and feel of the organization under new owner Jim Crane and new general manager Jeff Luhnow. They’ll move into the star-studded American League West next season, and recently submitted a more “traditional” uniform redesign to the MLB offices for approval.

Not liking this at all. Management screwed the pooch, not the coach. Fire them all, keep the coach, bring in young talent and see what Mills can do when given some potentially promising players. Now, if he still can’t win when given the right tools, then that’s a different story. But for right now, all that has been showed is that management won’t give him anything to work with, then blame him for the terrible outcome. That’s just brilliant.
